Married At First Sight star Alycia shows off amazing weight-loss transformation in before and after photos

You may recognise her as the gorgeous bride who was left heartbroken when her partner Mat revealed he was ending his Married At First Sight experience as he has "issues" to work on, but the star has taken to Instagram to share some happy news.

While she has not confirmed any relationship news, the star revealed a much greater project, how she has lost an impressive 42 kilos.

Taking to Instagram, Alycia shared a side-by-side shot of herself both before her weight loss journey and her most recent shot.

"SUPER nervous to post this, but here we go...(please be kind!),' she wrote to almost 30k followers.

"When the producers on Married at First Sight learnt about my weight loss journey, I was asked if I had any photos of myself at my biggest to include in my backstory, as it is a significant part of my life.

"I said no to sharing photos initially as it is hard to look at them myself let alone have others judge me!"

Alycia continued: "Despite my smile, I wasn’t a happy person in the photo on the left. I was in a bad relationship I didn’t have the strength to leave at the time, I was constantly criticised for the way I looked & rebelled by eating more.

"Literally the only reason I said yes to sharing my story, in the end, is because I was promised that it would help people & I really hope it can.

"People ask me how I succeeded in changing my appearance & I truly believe that a positive mind attracts wonderful things - this is where my transformation began. I grew mentally determined to become a healthy person purely for myself & my body followed.

"I got rid of anything/anyone toxic in my life, altered my diet & within 3 months I lost the first 12kgs. Over time I’ve managed to lose more than 30kgs & now feel the best I ever have!"
